That's not a path; it's "grist" used to uniquely identify the target.

Inside the build system. If you want to see a little more of what's
going on, try running jam with -d+2.

Oh, this is strange. It appears to be building condition.obj *after*
tryint to link the lib which depends on it! What's the result of running
jam with the -d+12 option?
